With this construcdiameter to iit snugly in the openings in the tion it will be seen that as the plunger-rod is outer ends of the caps of the stuffing-boxes, moved in one direction one inlet check-valve 45 so that the ends of the plunger, which enter 12 will open to admit water to its cylinder, the pumping-cylinders, lie close to but do not while the other inlet check-valve will close to touch the inner surfaces of the cylinders. prevent back pressure of water therethrough Thus as the plunger is reciprocated it will from its cylinder. At the same time the outletl check-valve of the rst cylinder will close to prevent return of water therethrough from the exhaust-pipe, and the outlet check-valve of the second cylinder will open to permit water to be forced from its cylinder through the exhaust-pipe. When the plunger is moved in the opposite direction, the valves 'are reversely operated and the functions of the cylinders are reversed. This operation is well understood by those skilled in the art.

In order to operate the plunger-rod 9, a lug 18 is formed thereon `or secured thereto at a point between the ends of the cylinders 5 and 6, and with this lug is connected a reciprocatory rod 19, the end portions of which have bearings in perforations 20, formed in upwardly projecting lugs 21 upon the threeway connections 11, one end of this rod 19 being adapted for connection with an operating means, as shown.

It will be seen from the foregoing that my improved pump is of an extremely simple construction, consisting practically of nothing but pipi-ng of the most ordinary kind, with the various joints-such as Ts, Ls, unions, and valvesof the most ordinary construction, which, however, have been assembled in such a manner as to produce a most satisfactory pump at a very triing expense. Practically the only special construction required by my invention is that of the two Ts, which are provided with upwardly-extending lugs 21, having perforations 20 for the passage of the operating-rod. The pump and cylinder are nothing but an ordinary piece of shafting having an upwardly-extending lug, with which the operating-rod is connected, said operating-rod extending through the bearings in the upwardlyextending lugs of the Ts. It is in order to permit these parts to be conveniently assembled or taken apart that the unions 111 and 16c are provided, and it will be seen that by simply removing these unions the pump may with the greatest facility be disassembled, if it should be found necessary, for cleaning or other purposes. The plunger is not in contact, and it is not intended to be in contact with the walls of the cylinder, this being avoided by the use of the packing-boxes at the ends of the cylinders. The absence of friction resulting from this construction greatly facilitates the operation of the device, the ordinary pistons being entirely dispensed with. Y

What is claimed is 1. A pump comprising a pair of Ts having upwardly-extending lugs, supply and exhaust pipes connected with said Ts and including check-valves, a suction-pipe connected by a T with the supply-piping, a discharge-pipe connected by a T with the exhaust-piping, unions connecting the members of the supply and exhaust pipings whereby the frame including the latter may be readily disassembled, cylinders connected with the Ts having the upwardlyextending lugs, a reciprocatoryvplunger engaging said cylinders and having an upwardlyextending lug, and an operating-rod engaging said lug and extending through bearings in the lug's extending upwardly from the Ts.

2. A pump of the class described comprising a pair of cylinders disposed in axial alinement, stuffing-boxes on the opposing ends of the cylinders, T-joints at the outer ends of said cylinders, having perforated lugs formed thereon, casings containing check-valves connected with the ends of the T-joints, elbows connected with said casings, pipes connecting the opposing ends of said elbows, said pipes including T -joints for the admission and expulsion of water, and unions whereby the pump structure may be disassembled, a reciprocatory solid cylindrical plunger extending through the stuffing-boxes into the cylinders and of less diameter than the latter, a plunger-rod having rigid connection with the plunger and extending through the bearings formed by the perforated lugs upon the T-joints at the outer ends of the cylinders.

In testimony that I claim the foregoing as my own I have hereto aiixed my signature in the presence of two witnesses.
